IIF条件下的SSRS和表达式

Question

Here is my output Here is what My Table looks like My code is supposed to sum the total but it is giving me incorrect results.

=SUM(IIF(Fields!BusinessDriver.Value = "Business Risk Reduction", 
Fields!BRRCalcRRPVETC.Value, IIF(Fields!BusinessDriver.Value = "Major 
Growth" OR Fields!BusinessDriver.Value = "Contractual Growth" OR 
Fields!BusinessDriver.Value = "Growth Improvement" OR 
Fields!BusinessDriver.Value = "Sustenance Efficiency", 
Fields!NPVonETC.Value, NOTHING))). 

Is there anything I am doing wrong? This code goes in my totals field.

Answer 1

Try using a switch() instead.

=sum(switch(Fields!BusinessDriver.Value = "Business Risk Reduction", Fields!BRRCalcRRPVETC.Value, Fields!BusinessDriver.Value = "Major Growth", Fields!NPVonETC.Value, Fields!BusinessDriver.Value = "Contractual Growth", Fields!NPVonETC.Value, Fields!BusinessDriver.Value = "Growth Improvement", Fields!NPVonETC.Value, Fields!BusinessDriver.Value = "Sustenance Efficiency", Fields!NPVonETC.Value, 1=1, 0))
